- On the occurrence of Phallocryptus spinosus (Milne-Edwards, 1840) in
Sicily (Crustacea, Branchiopoda)
Abstract: The distribution, status, and phenology of the anostracan Phallocryptus spinosus in Sicily are described. The only population of the species to date known to occur with certainty on the island inhabits a few temporary water bodies located within the Natura2000 site “ITA010006 - Paludi di Capo Feto e Margi Spanò”. In these sites, the species co-occurs with an interesting halophilous flora and crustacean fauna. Based on available data, the concentration of dissolved salts in the water bodies seem to be the main driver of the life histories of the co-existing populations of the anostracans Artemia salina and Phallocryptus spinosus.

- Class Trilobita (including agnostoids) from Argentine Precordillera
Abstract: This data paper inventories the records of 1763 trilobites (including agnostoids) from the Middle Cambrian inner and outer platform of the Argentine Precordillera (San Juan and Mendoza provinces). They were collected by Dr. Osvaldo Bordonaro and his colleagues between 1994 and 2013 and studied within the framework of scientific research. The specimens are stored in the Instituto Argentino de Nivología, Glaciología y Ciencias Ambientales (IANIGLA, CCT-CONICET Mendoza, Argentina), an official paleontological repository of Mendoza Province and are part of its Paleoinvertebrates Collection. The study of these trilobites contributed to the taxonomy of the group and allowed the establishment of important paleobiogeographic connections between Cuyania and Laurentia during the Cambrian. From a preliminary Microsoft Excel format, the dataset is now included in the Global Biodiversity Information Facility (GBIF, https://www.gbif.org), under the publisher CCT-CONICET Mendoza (Argentina),...

- The new Checklist of the Italian Fauna: Odonata
Abstract: Seventeen years after the publication of the last checklist of the damselflies and dragonflies found in Italy, an updated list has been compiled. This list reports 95 species belonging to 10 families and 38 genera and includes 2 national endemic and 1 sub-endemic species. Compared to the previous checklist, three species were removed, two subspecies were granted species status, and 10 species were added as new taxa for Italy. The checklist summarizes the current state of the knowledge on the geographical distribution of the Italian species with a regional detail. After the online publication of this dataset on the LifeWatch Italy website in 2021, some minor updates will be included in future releases. The newly discovered species are the result of increased exploration of the national territory combined with some possible range shifts, especially of Libellulidae species of Afro-Asiatic origin. This increased coverage of the country is the result of the efforts of many contributors....

- Marine mollusk thanatocoenoses along the coasts of the San Pietro Island
(South-Western Sardinia): a first reasoning on species composition and
biodiversity
Abstract: We conducted a study on the taxonomic composition and diversity of thanatocoenoses of marine mollusks sampled at five sites on a circum-Sardinian island (San Pietro Island, South-Western Sardinia). The aim was to measure the differences in terms of biodiversity by analyzing shells >2 mm. We collected 71 taxa (level of diversity γ) at five different sites. Four species represented more than half of the sample: Bittium reticulatum, Glans trapezia, Lucinella divaricata and Truncatella subcylindrica. We observed a high difference in the number of taxa (level of diversity α) between sites (range: 18-41; after normalization using the Margalef index: 9.45-15.84). The turnover of β-diversity between low-energy sites was lower than that among high-wave energy sites; low-energy wave sites located near shallow and extensive Posidonia oceanica beds showed the highest values of diversity metrics. Climatic factors related to wave energy (exposure...

- A new trans-Ionian spider species for the Italian fauna: Habrocestum
graecum Dalmas, 1920 (Araneae, Salticidae)
Abstract: The salticid spider Habrocestum graecum Dalmas, 1920, until now only known from Greece, is for the first time recorded in Italy. Observations on ecology and behavior are also reported and pictures of its habitus and genitalia are provided. Furthermore, the first DNA barcode sequence for H. graecum is produced and made publicly available. The species has been observed in Puglia, in South-Eastern Italy, and a trans-Ionian dispersal pattern is most likely the cause of its presence both in Greece and Southern Italy, as reported for other taxa with similar distribution in different animal groups.

- Taxonomy and distribution of the genus Santolina (Asteraceae) in Italy
Abstract: The Santolina chamaecyparissus complex includes 13 species of dwarf aromatic evergreen shrubs from the western Mediterranean Basin. Five native species occurring in Italy are currently accepted. Four of them are endemic to relatively restricted areas in the peninsula, whereas S. corsica Jord. & Fourr. is endemic to Corsica and Sardinia. The taxonomic treatments of Italian Santolina have been changing significantly in the past, probably due to the misinterpretation of naturalised populations of S. chamaecyparissus, a widely cultivated pentaploid species, which occasionally escapes from cultivation through agamospermy or vegetative propagation. In this study, we carried out the first quantitative morphometric and comparative niche analyses concerning the four species endemic to continental Italy (S. etrusca, S. ligustica, S. neapolitana, and S. pinnata). Morphometric analyses (PCoA, Random Forest, and...

- Age-related mobile digital divide in citizen science: the CSMON-LIFE
experience
Abstract: The amount of available Citizen Science data has increased significantly in the last two decades and has been used in several biogeographic studies as well. Citizen Science data are mostly collected through digital platforms, and especially mobile Apps. While the adoption of novel Information and Communications Technology (ICT) approaches potentially allow for a wider participation, recent studies have highlighted that the ability of making an intensive use of smartphones and mobile apps could decrease with users’ age. At the same time, data quality and commitment of volunteers in citizen science activities often increases with the age of volunteers. During the CSMON-LIFE (Citizen Science MONitoring) project volunteers provided their year of birth, thus allowing for inferences on the relation between age and data quality and retention rate. In this manuscript, a further investigation is carried out for understanding the potential effect of the digital gap that exists especially...

Italy)
Abstract: In the present study, we analysed the bee fauna reported in the Egadi Archipelago (circumsicilian islands). Field and bibliographical research carried out have allowed us to identify 40 taxa, between species and subspecies, belonging to five families: Colletidae (3 species), Andrenidae (9 spp.), Halictidae (4 spp.), Megachilidae (15 spp.), and Apidae (9 spp.). Twenty-seven species are reported here for the first time for the Egadi Archipelago, together with 13 species previously known from this archipelago, of which five are confirmed. For each species, details on collection data, distribution, and plants visited are given. Amongst the species recorded, Hylaeus duckei (Alfken, 1904) (Colletidae) and Osmia alfkenii Ducke, 1899 (Megachilidae) are new for Sicily. We include the first ‘Checklist of bees of Egadi’s Archipelago’ (40 species reported). Furthermore, the Apidae Nomada sicula Schwarz, 1974 is reported for the first time as a parasite of Panurgus...

Abstract: We present a data set on marine mites (family Halacaridae) in European waters. The data set gathers all the published records of marine mites from the North European Seas, Lusitania, Mediterranean Sea and Black Sea marine provinces, all belonging to the temperate North Atlantic geographical realm. The database includes 3006 records collected from 260 original publications. For each record, the dataset provides complementary taxonomic, geographical, and ecological information, as well as remarks regarding the sampling methods used in each study. We use this dataset to briefly discuss potential knowledge gaps and biases across marine regions and habitats. We hope that these data will provide a baseline for further studies in biogeography and ecology.

- First assessment of entomopathogenic fungi and nematodes in hot springs in
central Italy and first record of Pristionchus uniformis for the country
Abstract: Geothermal soils in Central Italy are characterized by high temperatures (up to 60°C), low pH values, and sparse vegetation. The biodiversity of entomopathogenic soil fungi and nematodes has never been assessed in these areas. Soil samples (N = 12) separated from each other by at least 100 meters were collected in the areas of Le Biancane Natural Park (Grosseto) and Sasso Pisano (Pisa). The Galleria bait method was used to assess the presence of entomopathogenic fungi and nematodes. A total of nine species of fungi and one nematode were isolated and molecularly identified. All these species came from samples collected in the immediate surroundings of geothermal spring, apart from one Beauveria pseudobassiana collected at about 16 meters from the nearest spring. Moreover, Pristionchus uniformis previously reported only from North America and few European countries is recorded for the first time in Italy.

Abstract: We present a data set reporting the checklist of the species belonging to the class Ascidiacea for the 9 Italian marine biogeographical units, updating the one previously published by Mastrototaro & Tursi in 2010. In detail, the updated checklist includes 138 taxa at species level (66 Aplousobranchia, 30 Phlebobranchia and 42 Stolidobranchia). Records refer to various marine habitats, including lagoons, harbours and semi-enclosed environments as well as deep habitats. The previous checklist reported 129 taxa (66 Aplousobranchia, 27 Phlebobranchia and 36 Stolidobranchia): in detail, 12 species were added, of which four newly described species, seven non-indigenous species and a new record for the Italian waters. On the other hand, three species reported in the previous checklist were removed: two because currently considered dubious, and one because its occurrence in the Mediterranean Sea is not actually confirmed. Finally, two species were renamed because they are considered...

- Seasonal bird assemblages in Dehesas (substeppic prairies with Quercus
suber) of North-Western Sardinia (Italy): A poorly studied landscape of
high eco-biogeographic interest
Abstract: Dehesas (i.e., substeppic prairies with Quercus suber) represent a poorly studied Mediterranean habitat type of high eco-biogeographic interest. Here, we applied a point-transect method along a yearly cycle (from spring to autumn), to focus on seasonal differences in bird assemblages inhabiting a Dehesas landscape in north-western Sardinia (Italy). We confirmed the presence of Mediterranean species with restricted ranges (e.g. Sturnus unicolor, Sylvia sarda). At the community level, seasonal patterns show significant differences among mean abundance, with a maximum in autumn and a minimum in summer. The highest values in autumn may be explained by the aggregations of wintering small passerines. Considering the univariate metrics of diversity, the number of species significantly differs among seasons, with the richest community in spring. Shannon-Wiener diversity and Margalef (normalized richness) were higher in spring and summer compared to autumn. Habitat...

- Urban orchids: an updated checklist of the orchid flora of Cagliari
(Sardinia, Italy).
Abstract: In the last decades, urbanization has led to drastic changes in ecosystems. Although this phenomenon is one of the greatest threats to biodiversity, cities can host a high richness of biological diversity. Several authors have recently emphasized the role of urban biodiversity in mitigating the effects of climate change and in providing benefits to citizens. In this study, I investigate the orchid flora of the city of Cagliari. Although the Mediterranean cities have a significant native flora, purely floristic works in urban ecosystems are still rare. During a thirteen-year study I encountered seventeen species, two subspecies and three hybrids. However, three taxa were no longer found. This inventory can support urban conservation policies and their implementation in the development of sustainable cities.

Abstract: The Scientific Committee for the Italian Fauna is managing the new checklist of the animal species of Italy. The previous checklist was published in 1993-1995 and included both protozoans and Metazoa (more than 57,000 species); the new project, which includes only Metazoa, started in 2020 and is aimed at updating the former checklist (with more than 60,000 expected species) by on-line datasets and data papers. The new checklist includes marine species recorded in the Italian seas, divided into nine marine sectors, within the Italian Economic Exclusive Zone, and terrestrial and freshwater species recorded in administrative regions, as well as in the three macro-regions (northern continental, southern peninsular and insular - Sicily and Sardinia - macro-regions). Records from geopolitical units biogeographically related to Italy (i.e., Canton Ticino, CH; Corsica, F; San Marino Republic and Vatican City) are also included. Over 180 Italian and foreign taxonomists have so far participated...

Cebrioninae, Drilinae and Lissominae
Abstract: This work presents an updated checklist and distribution of Coleoptera Elateridae of Italy. The data come from literature, from museums and private collections directly examined by the authors. The subfamilies Lissominae, Cebrioninae and Drilinae, which were previously considered independent families, are not included in the checklist, because there are not sufficient data. The distribution of the species is recorded and figured on maps at the provincial level, provided in a supplementary file, while the world distribution is given at the state level according to the Palearctic catalogue published by Cate in 2007 and the most recent works. The genus Pseudathous Méquignon, 1930 was resurrected for the species previously classified in the genus Hemicrepidius Germar, 1839 and Megathous nigerrimus (Desbrochers des Loges, 1870) is transferred to the genus Hemicrepidius Germar, 1839 according to recent taxonomic revision.

- The new Checklist of the Italian Fauna: marine Mollusca
Abstract: The mollusc fauna of the Mediterranean Sea is still considered as the best-known marine mollusc fauna in the world. The previous modern checklists of marine Mollusca were produced by joint teams of amateurs and professionals. During the last years the Italian Society of Malacology (Società Italiana di Malacologia – S.I.M.) maintained an updated version of the Mediterranean checklist, that served as the backbone for the development of the new Italian checklist. According to the current version (updated on April 1st, 2021), 1,777 recognised species of marine molluscs are present in the Italian Economic Exclusive Zone, including also the Tyrrhenian coasts of Corsica and the continental shelf of the Maltese archipelago. The new checklist shows an increase of 17% of the species reported in the 1995 Checklist. This is largely (yet not solely) due to the new wave of studies based on Integrative Taxonomy approaches. A total of 135 species (7.6%) are strictly endemic to the Italian...

Zizeeria karsandra (Moore, 1865) and Polyommatus celina (Austaut, 1879) in
Malta: A seasonal and multi-location investigation with additional notes
on the central Mediterranean area
Abstract: On the sole basis of morphometric analysis, it was routinely presumed that Pontia daplidice (Linnaeus, 1758), Zizeeria knysna (Trimen, 1862) and Polyommatus icarus (Rottemburg, 1775), occur in Malta. Recent DNA-based investigations (in-part combined with morphometric analysis) on islands and continental landmasses in the central Mediterranean shed light on the phylogeography of these and other, closely related, species. The present contribution focuses on seasonal and multi-location investigations within Malta of the genera Pontia, Zizeeria and Polyommatus. Voucher specimens from Sicily, Lampedusa and Spain are also analysed. A total of 43 specimens, in the following configuration are examined: Pontia (n = 21), Polyommatus (n = 11), Zizeeria (n = 11).

- Following the Apennines: updating the distribution of Formica clara and
Formica rufibarbis in Italy (Hymenoptera, Formicidae)
Abstract: Formica clara is an ant species that was historically confused with other congeneric species such as F. rufibarbis until recent taxonomic developments. Due to such misunderstanding, while F. clara is known to occur across a very large Eurasian range, its actual distribution in the Mediterranean is often scarcely known. The distribution of F. clara and F. rufibarbis in Italy is remarkably obscure since almost all records, which spanned across the whole Italian peninsula and Sardinia, were published between 1834 and 1969, at times when the two species were treated as a single taxon. The few modern records of the species testify the presence of F. rufibarbis in the Alps, and F. clara in the Alps, the Po Plain and Sardinia. Here we present some new distributional data on the two species, extending the geographic range of F. rufibarbis south to the Northern Apennines (225 km) and that of F. clara throughout...

in Lampedusa and Pantelleria islands (Southern Italy)
Abstract: Biogeography and the occurrence of small mammals are usually hard to investigate due to the small size and secretive habits of these mammals. Available data are particularly insufficient on minor islands and at national borders, where research efforts are usually scarce. Here we briefly updated the knowledge on murid rodents on two remote Italian small islands (Lampedusa and Pantelleria) at the southernmost Italian borders. During summer 2019, house mice and rats were sampled in Lampedusa and Pantelleria and molecular markers were sequenced for species identification. The new sequences of Mus domesticus were also compared with samples from previous works collected in Lampedusa, Pantelleria, and several localities in the Mediterranean basin. Moreover, our analyses provided the first genetic evidence of the occurrence of Rattus norvegicus in Lampedusa. To conclude, R. rattus was confirmed to be present in Pantelleria. The newly collected haplotype of...

census and population dynamic analysis through citizen involvement
Abstract: In the city of Genoa (NW Italy) three breeding species of Psittaciformes are known to occur: Psittacula krameri, Amazona ochrocephala and Amazona aestiva. We planned to update the knowledge of these alien species involving citizens in a project coordinated and managed by professional scientists and technicians from the Genoa University, the Natural History Museum “G.

The aims of the research are to highlight and quantify the impact on the urban environment of parrots and parakeets and evaluate which aspects of their presence are most perceived (negatively or positively) by citizens. The data obtained so far, on the basis of 227 observations, have allowed us to outline some aspects of the biology and habits of local Psittaciformes. We have related these characteristics to the impact that these species have on citizens, in terms of hygienic problems...

- Poor taxonomy and genetic rescue are possible co-agents of silent
extinction and biogeographic homogenization among ungulate mammals
Abstract: Genetic rescue is a measure to mitigate the effects of reduced genetic variation in endangered small, isolated (inbreed) populations by introducing new genetic variation into such populations. This is usually accomplished by translocating individuals from a related population, assumed to belong to the same, often polytypic species, into the endangered population. If, however, the taxonomic classification does not reflect the ‘true’ diversity, genetic rescue can have detrimental effects on the survival of the endangered population (e.g. outbreeding depression). Here we point to problems if erroneous taxonomy informs such translocating strategies. Actions that promote artificial admixture of evolutionary lineages may be ineffective, or they may homogenize existing diversity and biogeographic patterns instead of protecting them. The extreme result is to drive target species and/or cryptic lineages to silent extinction. We single out conspicuous examples to illustrate the negative...

Abstract: The epikarst crustacean fauna from four Sicilian caves (Conza, Entella, Molara, and Zubbia del Cavallo caves) and four caves in the Lessinian Massif in the Venetian Prealps (Covolo della Croce, Ponte di Veja, Roverè Mille, Buso della Rana caves) was recently investigated. The two groups of caves differ in their environmental conditions: the Sicilian caves are fossil except one which has an active branch; they are all fed by strongly intermittent and scarce rainfall peaking in the fall. The Lessinian caves are fed by more abundant rainfall, with two yearly peaks (May-June and October-November); two of them are active, one has a temporary stream, one is fossil. The crustacean fauna found in the epikarst drip of each of the studied caves is characterized by interesting endemic harpacticoid and cyclopoid copepods, and one bathynellacean syncarid, often collected in only one cave. Higher diversity of stygobiotic taxa was recorded for the Lessinian caves (9 species of copepods in...

- Cosmopolitism and endemism in free-living nematodes
Abstract: Most free-living nematodes should have a global distribution if they would follow general tendencies of microbial organisms. Information on free-living nematodes presented in this review demonstrates that this cosmopolitanism is less common than assumed by theory. While very large distribution ranges are observed in a number of nematode species, various examples of endemism are described for isolated units like islands, extreme environments and ancient pre-Quaternary lakes. Endemism is generally rare among microorganisms, but a typical observation for larger organisms. The biogeography of nematodes thus reflects their intermediate position between macro- and microorganisms and future studies on this interesting group may help identifying why the positive relationship between body size and range size observed in large animals shifts to a negative relationship in microbial organisms.

macroinvertebrates in Italian mountain lakes
Abstract: Macroinvertebrates play a key role in freshwater food webs, acting as major links between organic matter resources, primary consumers (such as bacteria), and secondary consumers (e.g.fish, amphibians, birds, and reptiles). In this paper we present a data set encompassing all geographic and historical data available on macroinvertebrates of the Italian mountain lakes from 1902 to 2016. The data set, divided per Italian mountain range (Alps and Apennines) and administrative region, covers more than a century of studies of many foreign and Italian scientists. The data set includes 2372 records and shows macroinvertebrate occurrence data in 176 Alpine and in 13 Apennine lakes, of which 178 of natural origin, 5 reservoirs, and 6 artificially extended. The data set lists 605 taxa, updated on the basis of their current taxonomic position. Only 353 taxa are identified at species level, highlighting the still poorly investigated biodiversity of Italian mountain lake macroinvertebrates....

- Endemism in historical biogeography and conservation biology: concepts and
implications
Abstract: Endemism is often misinterpreted as referring to narrow distributions (range restriction). In fact, a taxon is said to be endemic to an area if it lives there and nowhere else. The expression “endemic area” is used to identify the geographical area to which a taxon is native, whereas “area of endemism” indicates an area characterized by the overlapping distributions of two or more taxa. Among the methods used to identify areas of endemism, the optimality criterion seems to be more efficient than Parsimony Analysis of Endemism (PAE), although PAE may be useful to disclose hierarchical relationships among areas of endemism. PAE remains the best explored method and may represent a useful benchmark for testing other approaches. Recently proposed approaches, such as the analysis of nested areas of endemism, networks and neighborjoining, are promising, but need to be more widely tested. All these methods attempt to identify biogeographically homogeneous sets of areas characterized...

- Cave exploitation by an usual epigean species: a review on the current
knowledge on fire salamander breeding in cave
Abstract: The fire salamander (Salamandra salamandra) is a relatively common epigean amphibian, widely distributed throughout Europe, which usually gives birth to aquatic larvae. Even if epigean streams represent the most common places in which the species breeds, in some countries caves with underground waters are also used. To improve our understanding of the habitat features allowing successful breeding of salamanders in underground sites, we combined an exhaustive review of the available literature, especially the grey one, with direct observations performed from 2008 to 2017 in several natural and artificial caves of Lombardy, Liguria and Tuscany (Italy), Ariège and Provence (France). We provide a synthesis of published and unpublished caves in which the fire salamander breeding has been observed, along with a synthesis of the investigated ecological, behavioural and morphological traits. The use of underground sites is reported in several published papers and appears to...

- Tracking the invasion of the red swamp crayfish Procambarus clarkii
(Girard, 1852) (Decapoda Cambaridae) in Sicily: a “citizen science”
approach
Abstract: The first record of the red swamp crayfish in Sicily dates back to 2003 and, since then, the species seemed to be confined to a few localities in western Sicily. A small “citizen science” project carried out from November 2016 onwards led to the creation of the “Sicilian Procambarus working group” (SPwg), which aims at monitoring the distribution and impact of the species in Sicily. To date, the SPwg found the red swamp crayfish in five new sites on the island, thus doubling the number of local sites of occurrence. The new Procambarus clarkii sites lie in different river basins, some of them located several hundred kilometres from the invaded areas known to date, suggesting the existence of multiple independent releases of the species in the wild. The need of better informing the local population on the risks exerted by invasive species on biological diversity, and of carefully monitoring the impact of P. clarkii on the Sicilian inland water biota is...
